Problem

Let θ=13π4−2.35\theta=\dfrac{13\pi}{4}-2.35 (radians). (a) Reduce θ\theta to an equivalent angle lying between 00 and 2π2\pi radians. (b) Express the reduced angle obtained in part (a) first in decimal degrees correct to two decimal places. (c) Finally convert the result of part (b) into degrees–minutes–seconds form, rounding the seconds to the nearest whole number.
